Lie-able sofa

ABSTRACT

A lie-able sofa comprises a seat having a seat frame; in side the seat frame of the seat having at least one an oblong frame and at least one short frame; a hollow space being formed between the oblong frame and the short frame; a back frame uprightly installed to a backside of the seat; each bridge unit being formed by two connecting sheets being arranged at an upper side and a lower side; a nut and a stud serving to lock the two connecting sheets together; each connecting sheet having two cambered sheets at two sides thereof; as the two connecting sheets are combined, the cambered sheets of different connecting sheets being formed with a space for receiving the main support tube. By above structure, the oblong frame and the short frames are retained to the seat.

FIELD OF THE INVENTION

The present invention relates to sofas, and particularly to a lie-able sofa wherein the present invention is suitable for light-weighted lie-able sofa by assembling smaller parts with a lower cost. Bridge units are use for enhancing the whole structure of the sofa.

BACKGROUND OF THE INVENTION

Referring to FIG. 4, a prior art lie-able sofa is illustrated. The prior art sofa has a seat 1, a back frame 6, and two handles 3, 4 at two sides. The seat 1 is formed by two oblong frames 11. When a user sits or lies between the two oblong frames of the sofa, a hollow portion 90 between the two oblong frames are not supported so that the place will collapse. Thus it only supports a finite weight. Furthermore, the hollow portion 90 will make the user feel uneasy. To have a better supporting ability, the radius of the iron wires must be enlarged or more iron wires are used to be the space between the two oblong frames. However this will make the cost increased.

SUMMARY OF THE INVENTION

Accordingly, the object of the present invention is to provide a lie-able sofa, wherein the present invention is suitable for light-weighted lie-able sofa by assembling smaller parts with a lower cost. The bridge units have the effect of enhancing the whole structure of the sofa.

To achieve above object, the present invention provides a lie-able sofa which includes the following elements.

A seat has a seat frame and a plurality of legs 92 for supporting the seat.

In side the seat frame of the seat has an oblong frame and two short frames at two sides of the oblong frame.

Two sides of the oblong frame have two main support tubes arranged along two longitudinally sides of the seat frame. The short frame is arranged between one short side of the seat frame and a main support tube. The short frame is arranged between one short side of the seat frame and a main support tube.

A hollow portion is formed between the two main support tubes. A bridge unit is arranged across the two main support tubes. A hollow portion is formed between the two main support tubes. A bridge unit is arranged between the two main support tubes.

A plurality of iron wires are arranged across two longitudinal sides and two transversal sides of the oblong frame and two short frames so as to form as nets in the oblong frame and the short frames.

A back frame is uprightly installed to a backside of the seat. The back frame has an enhancing rod transversally arranged at an upper side of the seat so as to enhance the structure of the back frame. A plurality of connecting units are arranged between the back frame and the seat for retaining the back frame to the seat.

Two handles are at two sides of the seat. Each handle is connected between the seat and the back frame. Each handle has an enhancing rod below the seat.

Each bridge unit is formed by two connecting sheets are symmetrically arranged at an upper side and a lower side. A nut and a stud serve to lock the two connecting sheets together. Each connecting sheet has two cambered sheets at two sides thereof. As the two connecting sheets are combined, the cambered sheets are formed with a space for receiving the main support tube. Thus, by above mentioned structure, the oblong frame and the short frames are retained. Thus other than steadiness, the seat is also flexible and comfortable for lying and seating.

Similarly, the back frame is formed with an oblong frame and two short frames which has a structure like those used in the seat.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

Referring to FIGS. 1 and 2, the structure of the present invention is illustrated. The present invention related to a lie-able sofa which includes the following elements.

A seat 1 has a seat frame and a plurality of legs 92 for supporting the seat 1.

Inside the seat frame of the seat I has an oblong frame 11 and two short frames 12, 13 at two sides of the oblong frame 11.

Two sides of the oblong frame 11 have two main support tubes 111, 112 arranged along two longitudinally sides of the seat frame. The short frame 12 is arranged between one short side of the seat frame and a main support tube 121. The short frame 13 is arranged between one short side of the seat frame and a main support tube 131.

A hollow portion 90 is formed between the two main support tubes 111, 121. A bridge unit 2 is arranged across the two main support tubes 111, 121. A hollow portion 91 is formed between the two main support tubes 112, 131. A bridge unit is arranged between the two main support tubes 112, 131.

A plurality of iron wires 110 are arranged across two longitudinal sides and two transversal sides of the oblong frame 11 and two short frames 12, 13 so as to form as nets in the oblong frame 11 and the short frames 12, 13. A back frame 6 is uprightly installed to a backside of the seat 1. The back frame 6 has an enhancing rod 8 transversally arranged at an upper side of the seat 1 so as to enhance the structure of the back frame 6. A plurality of connecting units 7 are arranged between the back frame 6 and the seat 1 for retaining the back frame 6 to the seat 1. Two handles 3, 4 are at two sides of the seat 1. Each handle 3, 4 is connected between the seat 1 and the back frame 6. Each handle 3 has an enhancing rod 5 below the seat 1.

Referring to FIGS. 2 and 3, each bridge unit 2 is formed by two connecting sheets 20, 21 which are symmetrically arranged at an upper side and a lower side. A nut 23 and a stud 22 serve to lock the two connecting sheets 20, 21 together. Each connecting sheet 20, 21 has two cambered sheets 201, 211 at two sides thereof. As the two connecting sheets 20, 21 are combined, the cambered sheets 201, 211 are formed with a space for receiving the main support tube. Thus, by above mentioned structure, the oblong frame 11 and the short frames 12, 13 are retained. Thus other than steadiness, the seat 1 is also flexible and comfortable for lying and seating.

Similarly, the back frame 6 is formed with an oblong frame 61 and two short frames 62, 63 which have a structure like those used in the seat 1.

The present invention is suitable for light-weighted lie-able sofa by assembling smaller parts with a lower cost. The bridge units have the effect of enhancing the whole structure of the sofa.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
